Bed-spring fabric.



BEE-SPRING FABRE?.

Application filed December 241, 1915.

To all whom t may concern:

Be it known that I, Louis F. SCHJLLING, a citizen of the United States, residing at Salem, in the State of Ohio, have invented` new and useful improvements in Bed- Spring Fabrics, of which the following is a specication.

This invention relates to improvements in bed spring fabrics.

The invention proposes more particularly a bed spring fabric which is specially designed to be included in the equipment of a folding camp bed, such as is disclosed in my co-pending application Serial No. 76,409. It is to be understood, however, that the utility ofthe invention is not confined to the instance just referred to but that bed spring fabrics, in accordance with the inven` Ition, may be used in connection with any? particular construction of bed.

The objects of the invention, briey stated, are to provide a bed spring fabric which ma be used without amattress, and when so use will afford a comfortable resting surface for the occupant of the bed; which may be rolled into an exceedingly small compass; and which is inexpensive, strong, durable and sanitary. v

A. further object of the invention is to provide a bed spring fabric for use as stated which, whilev not in itself embodying any resilient elements, may be resiliently suspended from the end bars or rails of the bed similarly to any ordinary bed spring fabric and, hence, will insure the comfort of the occupant of the bed.

Embodiments of the invention are illustrated in the accompanying drawings, wherein:-

Figure 1 is a plan view of a bed spring fabric in which the features cf the invention are incorporated;

Fig. 2 is a detail cross-sectional view thereof on the line 2 2 of Fig. i; and

Fig. 3 is a detail sectional view showing a slightly modified construction.

Similar characters of reference designate corresponding parts throughout the several views.

vThe fabric shown in Figs. l and 2 includes two sheets of stent canvas or equiva- Spceication of Letters Patent.

lent material l and :2 arranged face to face and secured to one another at suitable transverse intervals by longitudinal rows of stitching 3. 'lhe sheets l and 2, when stitched together as stated, provide a support which may be of any desired longitudinal and transverse dimensions, preferably, tle dimensions which are standard for ordinary bed spring fabrics.

The'sheets 1 and 2 have under-turned longitudinal and transverse marginal portions a and 5, the longitudinal marginal portions 4 being secured by the rows of stitching 3 ladjacent the sides of the fabric and the transverse marginal portions 5 being secured by transverse rows of stitching 6 adjacent the ends of the fabric.

The longitudinal rows of stitching 3 are arranged in pairs, the rows of each pair being somewhat closely associated. The material between each two closely associated rows of stitching 3 provides ,a pocket 7 which extends 'longitudinallyof the fabric from end to end thereof and incloses a longitudinal flexible reinforcing element 8. .[he fabric is completed b the said reinforcing elements 8 which t snugly in the pockets 7 and at their ends project slightly beyond said pockets and are provided with eyes 9 through which the hoolclike extremities of the spiral supporting springs (not shown) may be engaged, these springs being, as usual, secured to the end rails or bars of the bed frame. The reinforcing elements 8 are preferably in the form of flat link chains of the well known construction and they eyes 9 of said reinforcing elements are provided, in the embodiment disclosed, by the openings in the end links ofthe chains.

ln Figs. l and 2 the mattress is unquilted and the portions of the canvas sheets bctween the reinforcing elements 8 lie against one another. 1With this construction, which is preferred, a blanket may be laid over the fabric to provide a uniform supporting surface for the occupant of the bed.

However, if desired, the fabric may be quilted and an example of a' quilted construction is shown in Fig. 3. In this case, the upper sheet of canvas l is left measurably full or loose between the reinforcing tudinally of the bed spring fabric and bear tlieweight of the user of the couch and thus, as their designation implies, protect the can vas sheets l and il, lt the same time, they insure the uniformity and efficiency of the support which the fabric, as a Whole, includ ing the canvas sieets, provides and 'thus prevent the fabric from sagging toward 'the center or throughout the area upon which the greatest weight is imposed The rein forcing elements S are preferably arranged at intervals of about two inches but their number for a bed spring fabric of given width is not absolute and may be varied Within certain limits. ln any event, a sufcient number of these elements should be,

employed to provide the requisite strength for the bed spring1 .fabric and to prevent sagging thereof. r.llie reinforcing elements 8, when provided in number sufficient for the purposes just stated, will not, however, cause any discomfort to the occupant of the bed in case a blanket, quilt, or the like, is placed over the fabric. 'l`hey will, more over, while preventing; sagging, permit of a measurable degree of flexibility and conse quent yielding of the fabric, thus insuring the ease of the occupant of the bed.

The bed spring fabric described, While having the advantages of strength and dura-- bility and of providing a uniform and comm fortable support for the occupant of the bed, can be rolled into exceedingly small. com-- pass. the equipment of a camp bed outfit, such as in disclosed in my co-pending application referred to, it may be rolled longitudinally into a compact cylinder, that is, cylinder having its major axis transverse to the bed spring fabric and having` a sufficiently small diameter to enable its convenient storage on (he running; board of an automobile. For this reason, the fabric is highly advantal,/.Azeous in all cases Where economy of spa/ce is a vital consideration.

The forni of fabric shown in Figs. l and 2 has the advantage that it can be readily washed or cleansed, should the .need ever arise. 'llie construction shown in lig may also be washed or cleaned as need aris s, although not so conveniently as the construction shown in ll ,'s. 'l and 2.

The chains d may be readily renewed should` it b e found necessary or desirable. These `chains are preferably retained by friction in the pockets 7, having,l a snug fit In said pockets, as stated. 'It is to be noted, however, that the form of the chain. linlrs Thus, Where the fabric is included in and the relation of the chains to the canvas sheets will preclude the chains from subn stantially 'Wearing the material of the pockets in which they are arranged.

Having fully described my invention, l claiml.n A bed spring fabric of canvas sheeting adapted to afford a resting surface for the occupant of the bed and having longitudinal parallel pockets enteinling,r from end to end thereof and arranged at regular transu i erse intervals, and flexible reinforcing and supporting elements extending' through said pockets and having projecting attachment terminals, said elements being in somewhat lose association with one another and of :such construction that the fabric may be rolled longitudinally into a compact cylm inder.
